### 错误 ###

Description: Parameter 0 of method customRouteLocator in com.powernode.config.RouteConfig required a bean of type ‘org.springframework.cloud.gateway.route.builder.RouteLocatorBuilder’ that could not be found.

### 原因 ###

可能是这个没有配置，大概率是maven的问题

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

### 解决办法 ###

可以clean一下maven，然后清除缓存重新启动一下IDEA，实在不行就重新新建一个一模一样的项目但是手写，然后一步一步的测试，我在解决这个问题的时候没有去排除任何的依赖
